Re: [Plplot-devel] wxPLplotDemo.cpp -- FIXED

Hi Alan


Success

The solution is to override the Show() function of the window, that is 
called in the demo.
So no need to modify the demo at all with a custom function call.


in wxPLplotwindow.h I just added this function

template<class WXWINDOW>
bool wxPLplotwindow<WXWINDOW>::Show(bool show)
{
   wxLogDebug("wxPLplotwindow::Show");
   CreateStream();
   WXWINDOW::Show(show);

}

where
CreateStream();
is a new internal function of the class that contains the code that is 
now in OnCreate()

the 2 files are attached
they contain a couple of debug messages

this is the sequence I get

11:13:52: Debug: wxPLplotwindow
11:13:52: Debug: frame->Create
11:13:52: Debug: wxPLplotwindow::Show
11:13:52: Debug: wxPLplotwindow::CreateStream
11:13:52: Debug: wxPLplotwindow::RenewPlot
11:13:52: Debug: Plot()
11:13:52: Debug: wxPLplotwindow::RenewPlot
11:13:52: Debug: wxPLplotwindow::RenewPlot
11:13:52: Debug: wxPLplotwindow::OnCreate
11:13:52: Debug: wxPLplotwindow::CreateStream
11:13:52: Debug: wxPLplotwindow::OnErase


as you can see the stream is NOT NULL when we get at
11:13:52: Debug: Plot()
